Chromosomes dance and pair up on the nuclear membrane
Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. view more (2009-11-16)
Novel chromosome abnormality appears to increase risk of autism
A multi-institutional study involving Massachusetts General Hospital (MGH) researchers has identified a chromosomal abnormality that appears to increase susceptibility to autism. view more (2008-01-10)
Rodent's bizarre traits deepen mystery of genetics, evolution
A shadowy rodent has potential to shed light on human genetics and the mysteries of evolution. view more (2006-09-18)
MU Researcher Identifies Possible Genetic Causes of Borderline Personality Disorder
According to the National Institute of Mental Health, borderline personality disorder (BPD) is more common than schizophrenia or bipolar disorder and is estimated to affect 2 percent of the population. view more (2008-12-17)
Cognitive dysfunction reversed in mouse model of Down syndrome
A study by neuroscientist William C. Mobley, MD, PhD, chair of the Department of Neurosciences at the University of California, San Diego School of Medicine, and colleagues at Stanford University Medical School has demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down's syndrome. view more (2009-11-19)
Evolution of Old World fruit flies on three continents mirrors climate change
Fast-warming climate appears to be triggering genetic changes in a species of fruit fly that is native to Europe and was introduced into North and South America about 25 years ago. view more (2006-09-01)
Genome duplication responsible for more plant species than previously thought
Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University Bloomington and three other institutions in this week's Proceedings of the National Academy of Sciences. view more (2009-08-13)
Parental Smoking Around Time Of Conception Linked To Reduction In Male Births (p 1407)
Couples who smoke around the time of conception could have a reduced chance of conceiving male offspring, suggest authors of a research letter in this week's issue of THE LANCET. The male to female ratio of children has declined substantially over the past few decades. The reason for this reduction is not clear, but it has been suggested that... view more... (2002-04-17)
Major genetic risk factor found for prostate cancer
Harvard Medical School researchers have identified a DNA segment on chromosome 8 that is a major risk factor for prostate cancer, especially in African American men. view more (2006-08-22)
Aberrations in region of chromosome 1q21.1 associated with broad range of disorders in children
Researchers have discovered a submicroscopic aberration in a particular region of human chromosome 1q21.1 that appears to be associated with a variety of developmental disorders in children. view more (2008-09-11)
Variation in bitter-taste receptor gene increases risk for alcoholism
A team of researchers, led by investigators at Washington University School of Medicine in St. Louis, has found that a gene variant for a bitter-taste receptor on the tongue is associated with an increased risk for alcohol dependence. view more (2006-01-10)
Chromosomal chaos in early embryonic development is linked to abnormalities in cytokinesis and spindle formation
Berlin, Germany: Abnormalities in the spindles (the bi-polar thread like structures that link and pull the chromosomes during cell division) of human embryos before implantation may be the primary reason for many of the chromosome defects observed in early human development, a scientist said on Wednesday 30 June 2004 at the 20th annual conference... view more...

New genetic biomarkers could predict coronary heart disease
New genetic markers may be able to predict whether a person is likely to have coronary heart disease (CAD) in the future. Research carried out by Dr. M. Balasubramanyam and Dr.V.Mohan at the Madras Diabetes Research Foundation (India) shows that people who are pre-diabetic or who have Type 2 diabetes have much shorter telomeres1 and, since these... view more...

Genetic Surprise Confirms Neglected 70-Year-Old Evolutionary Theory
Biologists at the University of Rochester have discovered that an old and relatively unpopular theory about how a single species can split in two turns out to be accurate after all, and acting in nature. view more (2006-09-08)
Genetic cause of speech defect discovered
Researchers at the University of Toronto (U of T), Capital Health's Stollery Children's Hospital in Edmonton, Toronto's Hospital for Sick Children and their international collaborators have discovered a genetic abnormality that causes a type of language impairment in children. view more (2005-10-20)
CSHL researchers discover three new genes that cause lung cancer
Researchers at Cold Spring Harbor Laboratory (CSHL) have discovered three genes that interact with cancerous results in 20% of lung cancers. view more (2007-10-09)
Scientists Identify Genetic Markers of Fear
An international team of researchers leaded by the Universitat Autònoma de Barcelona have found experimental evidence that the various manifestations of fear in animals are influenced by a specific place or region within the genome. The results, published in the latest edition of Genome Research, were obtained with rats, but the scientists... view more... (2002-04-26)
Gene variation is 'major genetic determinant of psoriasis'
A specific genetic region that has been increasingly identified as the strongest genetic link to psoriasis has an even more significant role in the chronic skin disease than has been suspected, University of Utah medical researchers show in a new study. view more (2009-08-28)
Scientists uncover mode of action of enzyme linked with several types of cancer
Scientists at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have discovered a key mechanism used by cells to efficiently distribute chromosomes to new cells during cell multiplication. view more (2009-06-04)
Link unraveled between chromosomal instability and centrosome defects in cancer cells
In a new study, Dana-Farber Cancer Institute scientists disprove a century-old theory about why cancer cells often have too many or too few chromosomes, and show that the actual reason may hold the key to a novel approach to cancer therapy. view more (2009-06-08)
